Gravitational-wave detectors on earth have detected gravitational waves from merging compact objects in the local Universe. In future we will detect gravitational waves from higher-redshift sources, which trace the high-redshift structure formation history. That is, by observing high-redshift gravitational-wave events we will be able to probe structure formation history. This will provide additional insight into the early Universe when primordial fluctuations are generated and also into the nature of dark matter.

来自二元黑洞的引力波作为结构形成历史的探针

地球上的重力波探测器已经检测到了合并本地宇宙中紧凑物体的引力波。将来，我们将检测到来自高红移源的引力波，这些重力波可追踪高红移结构的形成历史。也就是说，通过观察高红移引力波事件，我们将能够探究结构形成的历史。当原始波动产生时，这将为早期的宇宙以及暗物质的性质提供更多的见解。
